I am developing a links directory like Excite and Yahoo. One of my webpages would include the add url form. Having to filter those submitted websites check for relevant and duplicated websites everytime would be a tedious chore. If someone could suggest a script that will take care of it would be great. Furthermore, if those submitted urls could be saved in a database form and can be searched based on their title or keywords, then reported in alphabetical orders would be perfect.
